In the context of integrated parking brake calipers, the retraction of caliper pistons is a specific process influenced by the design of the braking system. Technician B's assertion is likely correct as it reflects the modern requirement for the correct technique when retracting caliper pistons in systems where the parking brake mechanism is integrated into the caliper.

Integrated parking brake calipers often feature a mechanical linkage that engages and disengages the parking brake using the same caliper assembly responsible for clamping the brake pads against the rotor. When servicing these calipers, it's essential to use the proper tool or method that accounts for this integration. Many of these calipers require the pistons to be retracted in a manner that also engages or disengages the parking brake mechanism correctly – often requiring the use of a scan tool or a specific procedure to ensure that both the brake pad clearance and the parking brake function are properly adjusted.

Understanding the specific function and design of integrated parking brake calipers is crucial, and technician B's understanding highlights the importance of using correct techniques when servicing these systems to prevent damage and ensure correct operation.
